Why the study?
Does magnetic resonance arthrography (MRA) improve the detection of femoral head-neck junction asphericity compared to conventional radiographs in patients undergoing surgical hip dislocation?
Population
58 selected hips in 148 patients who underwent a surgical dislocation of the hip
Comparison
Radial slices of magnetic resonance arthrography vs Conventional radiographs
Design
Cohort

Radiographs may underestimate asphericity; leaves open whether routine MRA alters surgical decisions or outcomes.
Does magnetic resonance arthrography (MRA) improve the detection of femoral head-neck junction asphericity compared to conventional radiographs in patients undergoing surgical hip dislocation?
Conventional radiographs underestimate asphericity of the femoral head-neck junction, which is better detected using radial slices of magnetic resonance arthrography.
Dudda et al. (2008) studied this question.
